RAIL-CHAIR.

T0 all whom it may conccm:

Be it known that I, CHARLES MALI1CH, residing at McKees Rocks, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rail-Chairs, o vvhich the following is a specification.

My invention relates to that type of rail joints of the boltless construction, embodying a joint chair and wedge devices for retaining the rail end in place in the chair.

The invention primarily has for its object to provide a very simple and elective construction of rail joint which can be easily and cheaply manufactured, and Which Will readily and efi'ectively serve its intended purposes. To this end the invention provides a metallic chair to rest on and be re cessed into the ties, the chair having a chamber to receive the rail ends and also to receive a wooden bed plate upon which the rail ends rest. The rail receiving chamber has parallel walls paralleling the web of the rail and spaced therefrom to receive wedge blocks of wood to retain the rail cen trally in the chair While at the same time giving sufiicient elasticity to the joint to prevent loosening and pounding of the parts. Means are also provided to prevent longitudinal creeping of the chair on the tie and 1neans are also provided for retaining the vvedges in position. Means are also provided to prevent lateral movement of the chair and to take up the strains on the tie recess walls.

In its more specific nature, the invention includes those novel details of construction, combination and arrangement of parts all of which Will be first fully described and then be specifically pointed out in the appended clairns, reference being had to the accompanying dravvings, in which Figure 1, is a perspective view of the invention. Fig. 2, is a horizontal section thereof. Fig. 3, is a cross section on the line 33 of Fig. 1. Fig. 4, is a detail side elevation of a part of the invention.

Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all of the figures, 11 designate the rails whose ends abut one another and rest in the chair 2. The chair 2 comprises a base 2 and a pair of upwardly extending parallelly disposed webs 2 2 whose inner faces 2 lie in paral- Specification of Letters Patent.

lel planes Which, however, are not parallel to the central vertical longitudinal plane of the chair, as a whole, but lie at an angle thereto to form wedge faces to coperate with similarly formed faces 3. of the wooden wedge blocks or keys 3, whose side faces 3 lie parallel with and engage the web 1 01: the rail, as clearly shown in Figs. 2 and 3 of the drawings. The chair webs 2 are braced tronc spreading by bracing webs 2, as sho-wn. The base 2 of the chair 2 has its chamber 2 eonforming to the shape of and receiving the rail base 1 and a wooden bed plate et upon which the rail ends rest.

In practice, the rail ends are placed in the chair 2, as shown in F igs. 1 and 2, after which the wedge keys 3 are driven into place from opposite ends of the chair until a tight fit is had.

In order to prevent the wedge pins or keys fro1n slipping out the inner faces et the webs 2 may be riflled, fiuted, corrugated or racked, at suitable intervals, as shown in Figs. 2 and 3, and in addition thereto, the web 2 may be bored and tapped as at 2 2 to receive set screws 6, one set of Which (those in the bols 2) exert a downward and inward force on the wedge keys 3, While the other set (those in hole 2 exert their force at approximately right angles to the wedges 3, thereby positively preventing the wedges from working loose.

In order to prevent spreading of the rails at the joint the chairs 2 are recessed at 7 into the ties 7 and to prevent longitudinal creeping of the chair 2 in the recess 7*, and also to relieve the wooden tie from lateral strains, due to the spreading tendency of the rails, when a train passes thereover, I provide a pair of spike grooves 2 on each side of the chair which are directed downwardly and outwardly diverging from one another downwardly, as shown in Figs. 3 and 4. It Will be noticed the holes all diverge from one another downwardly, that is, the holes on one side diverge downwardly toward the ends of the chair and toward the outer side thereof. Spikes 5 are held in the holes or grooves 2 and are driven into the tie and thereby seeurely bracing the chair 2 in its recess 7 from both lateral and longitudinal movement.

By making the wedge keys 3 and bed plate 4 of wood and the chair of cast or pressed or wrought metal, a strong joint is produced which Will be noiseless in operation as the contact of metal on metal is reduced t0 a minimum.

From the foregoing description taken in connection With the accompanying drawings, itis thought the complete construction, operation and advantages of the invention Will be readily understood by those skilled in the art to which the invention appertains, and I desire to say that slight changes in the detail construction can be made withont departing from the spirit of the invention or the scope of the appended claims.

\Vhat I daim is:

1. In a rail joint, a joint chair comprising a base having a rail base receiving cha1nloer and upwardly extending parallel webs spaced apart, and having their inner faces parallelly disposed to one another and held in planes at an angle to the central ver tical longitudinal axis of the chair and the web of the rail, rails having their ends held in said chair, wooden wedge keys interposed between the chair xveb and the rail xveb to secure the rail immovable, a wooden bed plate in the rail base receivingchamber under the rail ends, means for retaining said wedge keys in place, said means comprising protuberances on the inner faces of the rail chair Webs to bite into the keys.

2. In a rail joint, a joint chair compris ing a base having a rail base receiving chamber and upvvardly extending parallel webs spaced apart, and having their inner faces parallelly disposed to one another and held in planes at an angle to the central vertical longitudinal axis of the chair and the Web of the rail, rails having their ends held in said chair, wooden Wedge keys interposed between the chair webs and the rail web to secure the rail immovable, a wooden bed plate in the rail base receiving chamber under the rail ends, means for retaining said wedge keys in place, said means comprising protuberances on the inner faces of the rail chair webs to bite into the keys, and set screws tapped into the chair vvebs t0 engage the keys.

3. In a rail joint, a joint chair comprising a base having a rail base receiving chamber and upvvardly extending parallel webs spaced apart, and having their inner faces parallelly disposed to one another and held in planes at an angle to the central vertical longitudinal axis of the chair and the web 01 the rail, rails having their ends held in said chair, wooden wedge keys interposed between the chair webs and the rail web t0 secure the rail immovable, a wooden bed plate in the rail base receiving chamber under the rail ends, means for retaining said wedge keys in place, said means comprising protubrances on the inner faces of the rail chair webs t0 bite into the keys, set screws tapped into the chair webs t0 engage the keys, said set screws being arranged in pairs, one pair being directed downwardly and inwardlyagainst the keys and the other pair being directed at substantially right angles to the keys.

4. In a rail oint, a oint chair comprising a base having a rail base receiving chamber and upwardly extending parallel webs spaced apart, and having their inner faces parallelly disposed to one another and held in planes at an angle to the central vertical longitudinal axis of the chair and the web of the rail, rails having their ends held in said chair, wooden wedge keys interposed between the chair webs and the rail web to secure the rail immovable, a wooden bed plate in the rail base receiving chamber under the rail ends, means for retaining said wedge keys in place a tie having a transverse recess to receive said chair, said chair having a pair of spike grooves at each side, clownwardly diverging from one another, the grooves of one side diverging downwardly from those of the other side, and spikes held in said grooves and entering said ties to secure said chair thereto and brace it from lateral and longitudinal movement.
